About this study

The purpose of this study is to find out if digital media can be used to accurately evaluate a patient's range of motion after surgery, and save them trips back to the clinic for possibly unnecessary follow-up.

About this study

Displaced femoral neck fractures are one group of hip fracture patients that are commonly treated with cemented hemiarthroplasty (HA) or total hip arthroplasty (THA). In the elective hip arthroplasty population, the direct anterior approach (DAA) has shown to be effective in helping patients to quickly obtain high postoperative function. This approach has also been shown to be effective in arthroplasty for displaced femoral neck fractures in a few studies. However, the only studies that directly compare two approaches for hip arthroplasty for femoral neck fractures utilize the anterolateral approach (ALA) versus posterior approach (PA) or DAA versus PA. No studies of which we are aware directly compare the DAA to the ALA. The DAA and ALA are the two most popular approaches for bipolar hemiarthroplasty at our institution, so we are setting out to determine the differences between them.

About this study

Does tranexamic acid improve the perioperative care of those patients treated surgically for hip fracture by decreasing the proportion of patients requiring transfusion and decreasing total perioperative bleeding?

Study phase:

During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

The purpose of this study is to evaluate the hypothesis that the investigators current total joint regional anesthesia pathway of continuous femoral nerve block plus single-injection sciatic block with multimodal analgesia (MC1156-462rev0114) is more effective than two other pathways utilizing periarticular local anesthesia injections for numeric rating score (NRS) of pain with movement after total knee arthroplasty (TKA) on postoperative day 1 morning. The periarticular injections include one consisting of ropivacaine and the other consisting of liposomal bupivacaine (Exparel).

About this study

Of the three most commonly/routinely performed surgical technique of patellar resection during total knee arthroplasty performed at the Mayo Clinic, which results in the most symmetrically resected patella (knee-cap)?
